Molly is like that too. She just wiggles (I call it "all a quiver".) when I come home and really goes crazy when my daughter and grandkids come over. She also is beside herself wiggling when I take her over my daughter's house. My daughter has a pug who is a couple of months older than Molly. After she gets done all of her initial wiggling, then Molly and Leah run about until both are exhausted. It's cute to see her wiggle when she gets so excited like that. I hope she always stays a wiggler!
